      Hi

      I have some doubts and inconsistency in the documentation related to M5stick C push button mapping

      In the documentation we have
      https://docs.m5stack.com/#/en/core/m5stickc

      BUTTON A GPIO 37
      BUTTON B GPIO 39

      If I check the schematic I don’t see the mapping at all
      https://github.com/m5stack/M5-Schematic/tree/master/Core

      In the ESP Core schema there are no GPIO37 mapping on ESP32
      In the UART schema I found two buttons: one connected to GPIO 35 , the other one to EN net so PIN 5 of IP5306 / PIN3 of ESP32

      Really confuse

      More over the left button, the power ON/OFF button where is connected is the one connected to IP5306 ?

      Can someone provide clarification and provide a correct schematic ?

      thks
